THOMAS F. MCCAMBRIDGE, OF AKRON, OHIO.

VEHICLE WHEEL.

Application filed February 20, 1920. Serial No. 360,028.

To all whom. t may concern Be it known that I, THOMAS F. MCCAM- BRIDGE, a citizen of the United States, residing at Akron, in the county of lSummit and State of Ohio, have invented new and useful Improvements in Vehicle Wheels, ot

j which the following is a specification.

This invention relates to vcertain new and useful improvements in vehicle wheels of that type embodying means for fastening a demountable tire rim thereon, the tire rim ,being adapted for reception of a resilient tire, usually pneumatic. y

The primary object of this invention is to provide a iiXed rim for vehicle wheels which may be easily and cheaply manufactured from sheet metal and provided with radially movable members adapted toV be forced outwardly for engagement with the inner surface of a tire vrim in such manner as to effectively hold the `latter operatively positioned.

A further object of the invention is to provide a fixed wheel rim with a novel form of rim holding devices capable of being readily manipulated for releasing a tire rim for permittingremoval ot' the latter.

lilith the above general objects in view and others that will become apparent as the nat-ure ot the invention is better understood, the same consists in the novel form, combination and arrangement of parts hereinatter fully described, shown` in the accompanying' drawing and claimed.

In the drawing, forming a part ot this specification, and wherein like reference characters indicate corresponding parts throughout the several views.

Figure 1 is aside elevational view of a vehicle wheel having a fixed rim constructed in accordance with the lpresent invention,

Figure 2 is a radial sectional view there of taken upon one of the lines 2 of Figure 1 and shown on larger scale,

Figure 3 is a view similar to taken upon line 3 of Figure 1,

Figure d is a longitudinal sectional view taken substantially upon line 4t of Figure 2 and,

Figure 5 is a view similar to Figure 4 taken substantially upon line 5 of Figure 3.

Referring more in det-ail to the several views, the present invention comprises a fixed rim associated in the usual manner Figure 2 with the hub 5 having radial spokes 6. The liXed rim comprises an annular channel 7 disposed with its flanges projecting outwardly and provided with suitable sockets 8 in its base 9 for reception oli the similarly shaped outer ends or' thespokes 6, any suit able means being provided for rigidly retaining the spokes 6 operatively disposed with respect to the channel 7.

A plurality of radially movable members or shoes 10 are arranged at re ular intervals within the channel member and these radially movable members 10 are preferably formed of sheet metal and open at their inner sides. It will thus be seen that each member 10 is vin the form ot a segmental shoe, the side walls of which are spaced from each other such distance as to be slidably guided by the side flanges of the channel member 7. Each segmental shoe 10 is provided with a depressed central portion 11 in its outer side for reception of a nut 12 into which the threaded outer end of a screw 13 is threaded, said screw 13 being enlarged as at 14 to provide a shoulder bearing against the inner surface of the depressed port-ion 11. The screw 13 eXtends radially inwardly from each shoe 10 through an opening 15 provided in the base of the channel member 7.y and has a wing nut 16 threaded upon the inner end thereof e-Xteriorly ot the channel member 7 said wing nut being; retained against the inner surface ot' the base of the channel 7 by means of a fastening plate 17. The shank of the wing nut 16 is of circular form and fits within a similar opening provided in the plate 17, said wing nut being provided with a flanged base as at 18 which is overhung by the flange 19 ot' the retaining plate 17, and the Wingnut '16 is thus tree to be rotated although eli'e ctively :stained against movement laterally relative to or away from the channel member 7. The plate 17 may be secured to the base of the channel member 7 by means of rivets 20 or the like.

Each shoe 10 is oli'set longitudinally along one side as at 21 to provide a seatfor the inwardly projecting rib 22 which is usually provided upon the conventional form of tire rim 23, the rib 22 being positioned within the wider ilange 24 of the channel member 7. The narrower flange 25 of the channel member 7 is positioned to have the rib 26 of the rim 23 rest. thereon, said rib 26 being provided on the rim 23 adjacent .the :other side as `comparedftof the :i positiony of the rib 22.` It will thus befseenfA that by rotatingthe wing nuts 16, the screws` 13 may be caused to move radially inwardly and thereby impart a similar movement to the shoes 10. lhen the shoes 10 are moved inwardly sufiiciently the rim 23 may be slid laterally into its position" as clearly shown in Figures 2 and 3 whereupon the wing nuts f 16 may lbe rotated ina reverse direction for causing outward movements of the shoes l0 to the `positions thereof as illustrated also'in Figures 2 and 3v wherein the'shoes l() engageftherib 22 of the rim 23 and prevent lateral displacement of said rim from the telly, Thev outward movement of thef shoes dOalso servez-to hold the :rim 23 v'iniits tit Vwithin the adjacent shoe 10, the member v 29' `beingfprovided with base anges as at 30 which are riveted or otherwise suitably fastened to the base of the channel 7. The member 29V is provided with a central opening as at v31 into which the central depression l1 may pass when the shoe lOis radially moved either inwardly or outwardly as the case may be.

From the foregoing description, it is believed `that the construction and operation as well as the advantages ot the. present invention will be readily appreciated by thosev skilledA in the art.

It* will be understood that various changes maybe-made in the details of'construction herein speciiically described without departing from the spirit and scope of the vinvention as claimed.

I-Iaving thus described my invention what I claim as new and desire to secure by Letters Patent is 1.. In avehiele-wheelya tixed rim comprising an` integrally formed' 'annular channel disposed with its flanges projecting outwardly and adaptedto have its base fastened to the outer ends of the spokes of a wheel, segmental hollow metallic shoes disposed at intervals within said channel, said shoes providedwith inwardly projecting flanges adapted to be received between and radially `guided in sliding inward and outward movements by the side flanges of said channel, central screws rigidly fastened to said E'shoes and projecting radially inwardly through the base of said channel, and nuts having swivel connection with the base of said channel A member 'and"threaded upon said'screws whereby lrotation of saidVv nuts will causeradial movementjof said shoes forsecuringa tire 'rinr on'the fixed rim or releasingthe' same from the latter.

2.A In a vehicle-wheel in combination, a

`fixed rim comprising an annular channel disposedwithits tlanges'projecting outwardly and adapted to have its base tas'- vtened to theouter ends of the spokes of a wheel hollow, segmental metallic shoes provided" with inwardly`` projecting anges, said shoes disposed at intervals within said channel, a hollow segmental member iXedin said channel and received in the cavity of one of said shoes, central screws rigidly fastened to said shoes and projecting radially inwardly through said segmental member and the base ot said channel and nuts having swivel connection Withth base of said channelv member and threaded' upon said screws whereby rotation of said nuts will cause radial morcment of said slices for securing a tire rim on the-fixed rim or releasing the same from the latter, arsegmental member rigidly fastenedto said channel and slidably titting within one oiE said shoes for bracing thc latter against lateral or circumferential movementldue to the tendency of the tire rim to .creep or the like.

In testimony whereof I have hereunto set' my hand.
